there is a gap of 6 points now so it will be easier and closer, there are several games left in the season and if Arsenal lose or draw of course manchester city will benefit because manchester city are starting to be consistent in their winning ways to overtake Arsenal at the top of the table and take it, currently manchester city is preparing for the UCL match against Bayern, of course they have a lot to prepare.
The main requirements for arsenal to win EPL if the club must have more than 6 points gap. 6 points are not even enough to save arsenal from the city. City has 1 match remaining in addition if city will able to win against arsenal and manchester city will take the first place. I think that you can calculate it properly. It's about how manchester city is trying so hard to catch up arsenal. Arsenal is not yet safe. Liverpool was pushing arsenal to try even harder than before. Arteta must think so hard about how to win the upcoming matches.
The duel against city is a very important match that will determine the future of arsenal and manchester city. Three points are really important for now to the arsenal and city.
I wonder what strategy that pep will use to beat arsenal. that will become the match that has been waiting by all of epl lovers. The future of city will be determined from the result of that match.
